5Safety precautions
Bluetooth
®
Your phone has a Bluetooth interface. This
makes it possible to establish a wireless
connection with your phone and a headset,
car kit, or other Bluetooth-enabled devices.
In order to establish a secure link between
the devices and to prevent a third party
from having access to your phone, you
should observe the following points:
• The initial connection between two
devices, what is called "pairing", should
take place in familiar surroundings.
• Both devices must be able to identify
themselves one time by using a
password/PIN. To ensure sufficient
security, you should choose a 16-digit
number combination for a password that
would be difficult to guess (if a PIN has
not been assigned).
• An automatic connection acceptance
("connection without confirmation")
should only be used in exceptional cases.
• In general, only trustworthy devices
should be linked in order to minimise
security risks.
• You should restrict the "visibility" of your
phone if possible. This will make it much
more difficult for unknown devices to
establish a connection with your phone.
To do this, in the Bluetooth menu, set the
option Discoverable from Yes to No
(page 35).
• The name of your phone is transmitted in
a Bluetooth connection. The factory
default is the "BENQ EF71". The first time
Bluetooth is activated, or later in the
Bluetooth menu, you can change this
name (page 36).
• If Bluetooth is not needed, this function
should be deactivated.
Before using Bluetooth accessories, or a
mobile phone inside a vehicle, check the ve-
hicle user guide for any limitations on the
use of these products.
• Only use original batteries
and charging devices.
Otherwise you risk serious
damage to health and
property (battery explosion,
for instance).
• All batteries can cause
property damage, injury or
burns if a conductive
material, such as, jewellery,
keys or beaded chains touch
exposed terminals. The
material may complete an
electrical circuit and become
quite hot. Exercise care in
handling any charged
battery, particularly when
placing it inside your pocket,
purse or other container with
metal objects. Your batteries
are supplied with a protective
cover. Please attach this
cover to your batteries when
detached from the phone and
not in use.
• Do not dispose of batteries in
fire as they may explode.
Improper use will invalidate the
guarantee! These safety instructions also
apply to original accessories.
As mobile devices offer a range of
functions, they can be used in positions
other than the head, such as directly on the
body. In this case, the limits are met too.
